Hi @henrique.tx
I have downloaded toradex multimedia referance image Apalis-iMX8_Reference-Multimedia-Image-Tezi_6.4.0+build.8 from Toradex Artifactory web page.
And tested it with default settings for an HDMI screen. It works out of box.
/boot/overlyas.txt file which has overlay driver setting file is as follows:
root@apalis-imx8-14715897:~# cat /boot/overlays.txt
fdt_overlays=apalis-imx8_hdmi_overlay.dtbo apalis-imx8_spi1_spidev_overlay.dtbo apalis-imx8_spi2_spidev_overlay.dtbo
And changed it for a LVDS touch screen:
root@apalis-imx8-14715897:~# cat /boot/overlays.txt
fdt_overlays=apalis-imx8_panel-cap-touch-10inch-lvds_overlay.dtbo
It worked for the LVDS touch screen too.
Then I changed it for a dual screen usage.
root@apalis-imx8-14715897:~# cat /boot/overlays.txt
fdt_overlays=fdt_overlays=apalis-imx8_hdmi_overlay.dtbo apalis-imx8_spi1_spidev_overlay.dtbo
apalis-imx8_spi2_spidev_overlay.dtbo apalis-imx8_panel-cap-touch-10inch-lvds_overlay.dtbo
This time it crashes. This is Toradex multimedia reference image. Could you please help on this.
